Go play a Bard or Beastmaster Ranger or druid or a pure warlock without a martial class in the party and a caster without Act 3 legendary staff and clown gloves and get back to me how it feels when you're doing less than a third of the damage.
No idea how this relates to my post.

No idea what staff and gloves you talking about, so ... 50% is done :P
Can you be more precise which class 'i shouldn't play' so i can prove it's possible?
Possible does not relate to this post either. It's about comparison. You can probably complete the game with a full party of trickery clerics. Doesn't mean it's close to the efficiency of a party with strong martial classes in it.
I didn't said anything about martial classes in general, i said Paladin is overrated (read title, and OP post for clue).
Overrated IN RELATION TO WHAT. There you go, you made a comparison of class power. You made no comment as to whether paladin or fighter could complete a campaign. And now you're playing dumb about it. This was always a discussion about the comparative strength of classes. When someone states a class is OP, it's always in relation to the others.

The gloves is a broken piece of equipment that says "For spells with attack rolls to hit an enemy, you can take a -5 to the attack roll, and do +1d8 damage". This is rather weak with 90% of the attack roll spells in the game, kinda good with Scorching Ray because it has multiple projectiles, and absolutely broken bonkers with Magic Missile, because Magic Missile auto-hits, always, and it shouldn't even work with it, since it doesn't roll to hit.
And if you do that, you killed the gloves, because martials are getting gloves and feet with 1d6 rolls without a negative attack penalty roll, and once you remove magic missiles as the only spell that can compete with the single target damage of martials, you are going to have to massively buff single target lv5-lv6 spells, because the fact a single cast lv6 Disintegrate that has a DEX save or it does zero damage, and its damage range of 50-100 for a once per long rest use while the martials are swinging Balduran Greatsword for 40-50 damage per attack will put casters in the garbage bin, the only reason they aren't in a garbage bin to begin with right now is because of sorcerers and chain lightning and magic missiles. Wizards might as well be dead without the gloves and Art of War interaction, and warlocks are already in the dustbin as they're capped at lv5 spells and don't even get access to the good ones with 3 pathetic spell slots. Won't even touch caster druids, which are just as bad as warlocks.
